48 results about "Transcutaneous electrical nerve stimulation" patented technology

Transcutaneous electrical nerve stimulation (TENS or TNS) is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes. TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation although the term is often used with a more restrictive intent, namely to describe the kind of pulses produced by portable stimulators used to treat pain. The unit is usually connected to the skin using two or more electrodes which are typically conductive gel pads. A typical battery-operated TENS unit is able to modulate pulse width, frequency and intensity. Generally TENS is applied at high frequency (>50 Hz) with an intensity below motor contraction (sensory intensity) or low frequency (<10 Hz) with an intensity that produces motor contraction. While the use of TENS has proved effective in clinical studies, there is controversy over which conditions the device should be used to treat.

Electromechanical Manipulating Device for Medical Needle and Syringe with Sensory Biofeedback and Pain Suppression Capability

In an aspect, a medication delivering injector which includes a housing having opposing proximal and distal ends and an accessible internal cavity for inserting and removing a medicament container such as a syringe. The injector is designed to hold and manipulate a medication delivery device such as a large variety of standard and non-standard medical syringes with fixed or attached needles, assembled such that centrally located is a cylinder containing a liquid medicament and attached either permanently or removably to the distal end of the cylinder, is a hypodermic needle or cannula in fluidic communication with the cylinder. The needle can be from one-half inches to one-and-one-half inches in length in the illustrated embodiment and other sizes are possible by changes in scale of the injector. At the proximal end of the cylinder is an opening with an inserted seal or bung with an attached rod thus constituting a plunger. The central medicament containing cylinder could also be a standard medicament cartridge. Hereinafter, both are referred to as a “syringe”. A lid or access cover which, in an open position permits insertion and removal of the syringe into/from the housing in a horizontal fashion thus providing ease of loading. The syringe is inserted with the needle end toward the distal end of the housing and the plunger toward the proximal end of the housing. A movable carriage is disposed in the proximal end of the housing and slides in the axial direction forwards and rearwards such that a syringe, whose proximal end is gripped by the carriage, so moves with the carriage such that the needle exits the housing at the distal end of the housing and pierces the tissue of the patient prior to dispensing of the medicament, and then is retracted after the medicament has been dispensed by retraction of the carriage. Attached to the carriage is an actuator which pushes on the syringe plunger causing the medicament contained within the syringe cylinder to be dispensed through the needle into the patient's tissue. In one embodiment suitable for both removable needle and fixed needle syringes, the proximal end of the syringe including the syringe finger flange is gripped by an elastomeric flange grip which resides within the carriage, while the syringe distal end resides in and is supported by a “syringe guide” which is attached to the carriage and thus moved with it. In another embodiment which is so made to accommodate syringes with removable needles and their safe disposal, the syringe flange at the proximal end of the cylinder is gripped by an elastomeric flange grip which resides in the carriage as described above, while the syringe distal end is supported by a needle which resides in a removable disposable needle shield. The needle guide is biased toward the carriage and thus, the syringe body is compressed and guided as the carriage moves forward and rearward.
Both the movement of the carriage and the actuator are controlled by servo motors which are controlled by electronics and a microcontroller so operating such that speeds and accelerations are controlled smoothly and gently so as to avoid the stop/start motion of motors controlled by limit switches and simple electronics or the vibration and abruptness such as result from injectors powered by compressed springs or gas. Furthermore, the forces are adaptive to the loads imposed and the requirements necessary for the proper dispensation of medicaments with high viscosity or sensitivity to shear forces.
The housing, approximately midway between proximal and distal ends, is affixed by a hinge such that the device can be folded in half to provide for a more compact device to be stored and transported.
On the distal end of the housing are electrical sensor pads in communication with the microcontroller such that contact with the patient's skin and the angle at which the injector is held against the skin and the steadiness with which the injector is being held can be ascertained. Within the housing are a haptic vibrator and an audio speaker, both producing a vibration which is variable in pitch in such a manner that biofeedback is provided to the injector user as to the pressure, angle and steadiness with which they are holding the injector against the skin. This facilitates the action of injection oneself in the gluteus muscle where visual feedback isn't available to the patient.
Multiplexed onto the electrical sensor pads, is a TENS (Transcutaneous Electrical Nerve Stimulation) generator which is operational (at the user's choice) just before and during the injection to interrupt or quench the pain of tissue perforation often accompanied with needle injections.
Contained on the surface of the housing such as on the access cover, is a display such that user menus, device state, directions, and battery charge status, etc. are displayed. Also contained on the surface of the housing, on the proximal half, are buttons which control the menus and selections that are shown on the display. These selections provide for the user to set such parameters as hypodermic insertion speed and medicament dispensing speeds, the preferred mode of user biofeedback which can include: speech mode (which can be accompanied by musical themes and ringtones, plus variable pitch tone and haptic vibration), MP3 mode (which has speech muted but includes musical ringtones and variable pitch tone and haptic vibration), and haptic mode (which is haptic vibration and audio tone queues needed for injector position biofeedback and readiness), plus mute mode (which provides no audio but the haptic vibration remains), and none, which provides no vibrational biofeedback, yet the display information always remains available.
Also contained on the surface of the housing on the distal half, is an “injection initiate” button which causes the sequences required for performance of an injection to occur if said button is “enabled”.
Contained within the electronics and its operating program is the ability to audibly play pre-recorded human speech in any language such that: directions in the form of consecutive steps which are required to load the medicament container (syringe) into the device, consecutive steps to perform an injection, steps to remove and properly dispose of parts, to alert of device status and menu choices, etc. can be played through the audio speaker. Also contained within the electronics and program is the ability to play musical ringtones as a distraction during the needle insertion and injection or when a scheduled injection alarm is reached, or calming human voice exhibiting bedside manner during the needle insertion and injection.
Also contained within the electronics and software is a real-time clock-calendar which can store a patient's injection schedule and play a musical ringtone as an alarm as each scheduled injection becomes due. Also contained within the electronics and software are the ability to communicate with a personal computer through a USB port, which can also charge the injector's rechargeable battery. The battery in one embodiment, consists of three AAA batteries which can be rechargeable or non-rechargeable. The USB port in combination with an application running on the personal computer, is used to download the injection schedule into the real-time clock-calendar and to download ringtones and musical themes of the user's choice and to download foreign language sets for the pre-recorded human language feature.
The injector can be further equipped with the capability to aspirate the tissue by drawing back on the plunger thus creating a vacuum into which fluids will flow. These fluids enter the syringe cylinder where they can be checked for the presence of blood by optical absorption in the red spectrum. This information is useful in the instances where intramuscular injections are to be given with drugs whose ‘Full Prescribing Information’ instructs the patient to aspirate and check for blood in the syringe which indicates that the puncture of a vein has occurred, and if so detected, to abort the injection and then re-inject into a different location.

Synthetic traveling wave transcutaneous electrical stimulation device

A transcutaneous electrical nerve stimulation device for treating a user's lower back pain or discomfort is provided. The inventive device comprises a stimulation pad with an array of electrodes therein. A controller communicates with the electrodes to energize/de-energize them in a patterned, sequential manner. The patterned actuation of the electrodes in a sequential fashion provides electrical impulses to the patient's skin, simulating a transverse wave motion. The transverse wave motion simulation provides the user with the effect of the electrical stimulation combined with the mechanical tissue stimulation received in traditional massage therapy, resulting in improved pain and discomfort relief. The device may use programs stored in the controller. Alternatively, the user may manually actuate one or more electrodes as well as manually move the electrode actuation to concentrate on a specific lower back region using an electrostatic touch pad or the equivalent. The user may also use voice commands to access the stored programs, move the electrode stimulation region, change the electrode actuation intensity and/or dwell time. The device may store the user's manually-generated routines for repeating when desired. A visual display may provide feedback to the user regarding the electrode actuation position and pattern.
